Chris Sutton last night insisted the “inflammatory” and “childish” remarks of Dave King have disrespected the whole of Scottish football.

The Rangers chairman has sparked massive controversy by claiming four of the last six titles won by Old Firm rivals Celtic are worthless because the Ibrox club were not competing against them in the top flight.

King insisted that, as far as Rangers are concerned, Celtic don’t have six-in-a-row.

But although the remarks appeared to be aimed directly across the city, Sutton says the rest of the Scottish game has also been dismissed and discredited by King’s insulting comments.

Sutton believes King's comments have been a slur on the whole of the Scottish game

He said: “Celtic have won six in a row so far and have deserved to do so – just as Rangers deserved to win their nine in a row.

“To suggest anything otherwise is to behave like an infant.

“He has been childish. He needs to grow up and stop coming out with rubbish like he has.
